[Multipart message — attachments visible in raw view] — view raw

Hi,

After microcode update, for signature=0x306a9 upgraded revision should be
0x1f but dmesg shows wrong revision any ideas what went wrong.

i have upgraded microcode using apt-get install iucode_tool.

In intel release notes, came across the below notes which says that it
should upgraded to 0x1f.
IVB E2 6-3a-9:12 1c->1f

according to the log, firmware was updated from 0x17 to 0x1b
which version of intel-microcode do you have installed?
did you reboot after upgrading the package?
